Privacy Policy
Effective date: October 16, 2026

Covered services
| Service | Platform | App identifier |
|---|---|---|
| Mewkari | iOS · Android | com.futurejelly.mewkari |
Where a service is handled differently, the relevant section names it.
1. Information we collect
The Service does not require registration and never asks for your name, email or phone number. If you want to move your progress to a new device, you may optionally link an Apple or Google account. The following information is generated or collected while you use the Service.
| Category | Details | How |
|---|---|---|
| Device identifier | An account identifier derived from a device-unique value provided by the operating system | Generated on first launch |
| Gameplay data | Stage progress, currency and item balances, settings, save data | Automatically during play |
| Purchase data | Store transaction ID, product ID, items granted (we never receive payment card details) | On in-app purchase |
| Account link data (optional) | Apple or Google account identifier, Apple refresh token (to revoke the Apple link when you delete your account), device credential (a random value the app creates; the original stays on your device and our server keeps only a hash), account switch records (internal account numbers, time and choice) | When you link an account in Settings. Identifiers and tokens come from Apple or Google; the device credential is created by the app and switch records by our server |
| Name and email (optional, not stored) | Name and email address that may be contained in the Google sign-in token when you link a Google account. Our server verifies the token and stores the account identifier; it never uses or stores the name or email. Apple linking does not request name or email | When you link a Google account |
| Device and app data | Device model, OS version, app version, language, app instance ID, push notification token | Automatically |
| Advertising identifier | Android Advertising ID (GAID); iOS IDFA only if you allow tracking | Automatically |
| Usage and crash data | In-app events, ad impressions and clicks, crash logs, IP address | Automatically |
| Support inquiries | Email address and message you send us. The app pre-fills the message with app version, OS, device model, language and your user ID (server account number) | Sent by you |
2. How we use it
| Purpose | Data used |
|---|---|
| Providing the Service and saving/restoring progress | Device identifier, gameplay data |

| Push notifications about announcements | Push notification token |

3. Retention
- Device identifier, gameplay data, push token and account link data (except account switch records): until you run "Delete my data" in the app or ask us to delete them. Deleted immediately from our servers. For an Apple-linked account we ask Apple to revoke the link; if that fails we keep only that refresh token aside, retry up to 7 more times, then discard it.
- Name and email: never stored; processed only transiently while the Google sign-in token is verified.
- Account switch records, and a previous account that was disconnected from this device when you loaded another account and has no remaining linked sign-in (its gameplay and purchase data): kept for 5 years from the switch to preserve purchase records and prevent fraud, then deleted.
- Purchase data: 5 years for payment records and 3 years for dispute records, as required by Korean e-commerce law.
- Access logs (IP address): 3 months, as required by Korean telecommunications law.
- Support inquiries: 3 years after resolution.
- Data held by third-party services (section 4) is retained under their own policies.

We do not sell your data. The following providers process data on our behalf; all are located outside Korea.

5. Advertising identifiers and your choices
The Service shows ads and uses advertising identifiers for frequency capping, measurement and personalization. You can limit this on your device.
- iOS: Settings > Privacy & Security > Tracking. Turning off "Allow Apps to Request to Track" withholds the IDFA.
- Android: Settings > Google > Ads. You can delete your advertising ID or opt out of ad personalization.
6. Your rights and data deletion
- Settings > Delete my data in the app immediately and permanently deletes the current account's game data on our servers and your device, and its account link data, including purchased currency and items. Account switch records and any Apple refresh token awaiting revocation follow section 3.
- If we have no way to revoke your Apple link, the app tells you so. Because revocation can also fail, you can always remove the link yourself in Settings > [your name] > Sign in with Apple, then select Mewkari.
- You may request access, correction, restriction or deletion by emailing [email protected]. Because we cannot find your account by name or email, please include the user ID that the in-app "Contact us" feature adds to your message so we can locate your data.
- If you are in the EEA, UK or another region with data protection law, you also have the right to lodge a complaint with your local supervisory authority.
7. Children
The Service is not directed to children under 14 (or the age of digital consent in your region) and we do not knowingly collect their personal information. If we learn we have, we delete it promptly.
8. Security
All traffic between the app and our servers is encrypted with TLS. Server access is restricted and logged. Payment details are handled by the app stores and never stored by us.
